Patent DE-2612610-A1 (DE)
Title: Oscillating plate mach. for cont. mastication of moulding materials - suitable for bulk or powdered rubbers etc.
Inventor: BRAND WILHELM
IPC: B29B7/36
Filed: 1976-03-25
Abstract: A mastication machine for working and homogenising moulding materials, includes rubbers, where the working chamber comprises an open ended passage between a stationary base plate having an undulating surface and a top plate with a complementary undulating surface moving with cyclic oscillation between the crests of the base plate profile, producing the effect of a linear peristaltic pump with multiple lobes. Suitable in principle for masticating any dry blend compsn., including powdered or crum materials. Readily accepts a wider range of particle sizes than screwfed machines. Progressive pumping and discharge of the material occurs continuously, in contract to batch mixing in rotary kneading machines.
Patent DE-2615339-A1 (DE)
Title: Sulphurous effluents purification - by treating with an alkaline chlorite soln.
Inventor: HUENICKE WOLFGANG
IPC: C02F1/76
Filed: 1976-04-08
Abstract: Effluents (water or gases) contg. sulphurous cpds., esp. H2S, mercaptans, sulphides, SO2 and/or sulphites, are treated with an aqs. soln. of alkali(ne earth) metal chlorites at pH >9. A pref. combination is NaClO2 in KOH or NaOH. By working in alkaline media, problems associated with instability of the washing liquid are overcome as well as the tendency to form dangerous cpds. The medium affords a large buffer capacity so that the plant operates without extensive regulating and measuring auxiliaries, esp. useful with smaller units. At pH = 11.5, the efficienty is high enough to remove completely all noxious substances and/or require a very short dwell time.
Patent DE-2615492-A1 (DE)
Title: Reactor safety valve immersed blowdown pipe - has two outlet groups producing phase displaced gas pulses
Inventor: FREDELL JAN DIPL ING
IPC: G21C9/00
Filed: 1976-04-09
Abstract: A blowdown device for a reactor safety valve is connected at one end to the safety valve and is immersed at its other end in a water tank, the immersed part of the blowdown device comprises first and second groups of outlet openings. The speed vectors of the medium as it emerges from the first outlet openings cross the corresponding speed vectors of the medium emerging from the second group of openings. Since the two sets of outlets are at a substantial distance from each other, there is a phase difference between the pressure pulses emerging from them. Since however, the orientation of these pulses is along intersecting lines, the resultant effect is that two basic clouds of gas are initially produced when the blowdown commences, these clouds approaching close to one another but possessing different phases. This results in a considerable pressure balancing of the gas clouds in the water, without any substantial inertia blanket of water between the clouds. This considerably reduces the forces acting upon the immersion tank itself, esp. during the initial blowdown phase when air is first compressed and then discharged under expansion into the water.

Title: Instrument stand with extending and retracting legs - uses sliding profiled legs clamped by brackets with clamping screws
Inventor: MEINUNGER HELMUT
IPC: F16M11/26
Filed: 1976-04-20
Abstract: The instrument stand has extending and retracting legs which consist of simple open profiles. All these profiles can be made with the same tooling and hence they are economical to make.

Two profile sections (1, 2) are held together by a clamping bracket (3). This bracket has folded edges for holding the open edges of the profiles. The profiles are clamped in the brackets by a clamping screw (4).

Title: Nonmetallic pipe with metallic detection strip - has flat cross section to improve contact with earth at one side of strip
Inventor: KOTZENT HANS JOHANN
IPC: F16L1/11
Filed: 1976-07-15
Abstract: Non-metallic pipe intended for underground applications has a metallic strip secured to its outside to make possible the location of the pipe by an electro-acoustic detector. The strip (2) is of flat cross-section one side of which is adhered to the pipe (1) while the other side is open to the environment. The strip therefore has a good surface area in contact with the earth so that even if the strip should break a sufficient electrical continuity is maintained through the surrounding earth to make it possible to complete the circuit of the detecting system through a probe inserted into the ground.

Patent DE-2703298-A1 (DE)
Title: Rotor with cutting blades for snowplough - has auxiliary blades directing snow through centrifugal blower
Inventor: LAINE JUSSI KALEVI
IPC: E01H5/09
Filed: 1977-01-27
Abstract: The rotor for a rotary snowplough is designed to make more efficient use of its power by having cutting blades (1) so shaped that they accelerate the snow particles along the inner face of each blade. The snow is then ejected through an opening in the housing which encircles the rotor. Since the outer diameter of the cutting blades (1) is less than that of the centrifugal blades (2), auxiliary blades (3) are attached to the support ring (7) in order to direct the snow into the centrifugal blower. These auxiliary blades keep the space between the housing and rotor free of snow since they generate an airstream through openings in the rotor disc (6) near the hub (5).
